Researchers have developed a genetic screening tool that identified two key factors that allow the influenza virus to infect human lung cells. The technique uses new gene editing tools to create a library of modified cells, each missing a different gene, allowing scientists to see which changes impact their response to flu. This in turn could identify potential targets for antiviral drugs.
